DVD Shrink is good, I love using it, even though i am pretty new @ creating DVD backups. It only takes a few minutes to learn and, if you want to, you can use AnyDVD (if you have it) or, you can use
DVD Decrypter and Shrink, I know Shrink is supposted to decrypt the DVD by itself but, if you have problems with a DVD then use Decrypter and Decrypt the DVD (in ISO or File mode depending on if you have a virtual drive on your PC, ISO's can be placed on Virtual Drives) Then, use Shrink to trim the movie if you want and get rid of all the junk off of the original (such as extra langs, trailers etc.) Shrink also shows you how much compression is needed to burn the DVD. I know CloneDVD 2 does that too.
